Environment

VMware vSphere ESXi 6.0

Cause

This issue occurs because there is a failure in the processing to release the lock between hostd and sdrsinjector.

Resolution

This issue is resolved in ESXi 6.0 Patch 06 or later.



Workaround:
To work around this issue stop sdrsinjector.

• Run the following command with ESX Shell or SSH, and then stop sdrsinjector.

 

# /etc/init.d/sdrsinjector stop
 

Note: By default, the automatic startup of sdrsinjector is enabled upon the startup of ESXi. After ESXi is restarted, you need to stop sdrsinjector again.

• The automatic startup of sdrsinjector can be disabled by the following command.

 # chkconfig sdrsInjector off

• After disabling sdrsinjector, check the setting with the following command. You can see the configuration is changed to 'sdrsInjector  off'

 # chkconfig sdrsInjector 

  sdrsInjector    off
